Heard that rumour too, if you watch Heat, its a credible rumour, but Heat was a remake of LA Takedown which was made in 1989, also by Michael Mann. The F&M and weapon handling in LA Takedown is as professional and pre-dates GW1. So unless AMcN was moonlighting in the late 80s it seems unlikely (well either that or it was money for nothing).

LA Takedown is a better film for the lack of a big name cast and the Hollywood need for a happy ending.
